If renting a red-box movie costs 1.29 per night and one fee of 0.50
For three nights it would be 5.37 because you add 1.29 and 0.50 because its a one time fee then multiply the sum by 3 since you have the movie for 3 nights
Now for 10 nights you do the same add 1.29 and 0.50 then multiply by 10 which gives you 17.90
So 3 nights will cost $5.37
And 10 nights will cost $17.90
